MACHINE FOR FASTENING BUTTONS ON SHOES.

Application filed February 11, 1915.

To all whom it may concern Be it known that I, ISAIAH I. GUTTMAN, asubject of the King of England, residing at Minneapolis, in the countyof Hennepin and State of Minnesota, have invented certain new and usefulImprovements in Machines for Fastening Buttons on Shoes, of which thefollowing is a specification.

My invention relates to machines for fastening buttons on shoes, and hasfor its object to provide such a machine in Which the rivet-s arecontained in a magazine of the machine in the form of straight wireseach of a length exactly right to provide a fastener, together withmeans to feed the straight fasteners through the eye of the button,which has previously been brought into position, and thereafter to formthe fastener, first into the form of a staple and then to clamp thefastener through the material of the shoe to secure the but ton inposition thereon.

The full objects and advantages of my invention will appear inconnection with the detailed description thereof and are particularlypointed out in the claims.

In the drawings, illustrating the application of my invention in oneform,Figure 1 is a side elevation view of a machine embodying myimprovements. Fig. 2 is a front elevation view of the parts shown inFig. 1. Fig. 3 is a view partly in section of the parts shown in Fig. 1with said parts in a different position. Fig. 4 is a view similar toFig. 3 viewed from the other side of the machine. Fig. 5 is a completesectional view of the machine as shown in Fig. 1. Fig. 6 is a frontpart-sectional view similar to Fig. 2. Figs. 7, 8 and 9 are fragmentarysectional views showing the successive different positions of the stapleforming and fastening mechanism whereby the straight wire fastener isformed into the staple and is fastened with the button upon the shoe.Figs. 10 and 11 are rear views of the machine showing the parts forinserting the wire fastener members through the button-eye in twodifferent positions. Fig. 12 is a view of the fastener members beforeoperation within the machine.

My invention comprises a casing 15, which may be a single member formedwith upper separated plates 16, 17 with a space 18 between the same fromwhich extends a channel 19, as best shown in Fig, 5. The

Specification of Letters Patent.

23, adapts the machine to be secured to a table or counter. Upon thefront wall of casing 15, which is shown as slightly oblique to thevertical, is a channel member 21 having a central slot 25 through Iwhich the eyes of buttons 26 project. The

channel guides the buttons into position, as best shown in Figs. 3 and4. The buttons are in general fed down by gravity. Having reference toFigs. 3 and 5, the means of releasing the buttons one at a time and ofholding them in position during the staple-inserting and form-operationwill be apparent. As indicated in Fig. 5 the parts are in normalposition. The release member comprises a lever 27 fast on a pivotedshaft 28 which is formed with a concaved head 29 adapted to receive thebody of the shoe button, as shown in Fig. 5, and restrain forwardmovement along the slot 25 of such a button. Pivoted to lever 27 is aclamping arm 30 which is provided with a head 31 having a curved face 32engaged by a roller 33 on a spring 34:, which, as shown in Fig. 2, iscarried around a. pair of posts 35 and 36 and anchored at 37 and 38 tothe casing 15. The head also has on the underside thereof a stop fingeri0, and by means of the spring 33 said head and the stop finger 10 areheld in engagement with the button 26, which has been released byoperation of lever 27, and hold this button clamped in position toreceive the straight metal fastener, as clearly shown in Fig. 5. Whenthe parts are moved, as hereinafter to be described, from the positionshown in Fig. to that shown in Fig. 3, the socket 29 on the end of arm27 will be oscillated so as to free a. button 26. In the meantime, theshoulder 11 at the point of junction of head 31 with arm 30 will haveengaged a cam surface 42 on an extension 43 of the guideway 24, whichwill have lifted this shoulder out of the path of the descending button,the stop finger 'being engaged by the button, which holds the same fromfurther downward movement, as shown in Fig. 3. Upon return movement ofthe parts, effected by spring 34, the button will be moved into positionand clamped between stop piece and shoulder 41, as indicated in Fig. 5.In this position the eye of the button 26 is held to receive one of thefastener members 44, indicated in detail in Fig. 12. These members arepieces of wire of the requisite length to form a complete fastener whichare provided with pointed ends and a diminished central portion 46. Thefasteners are contained in a magazine 47 at one side of the machine, asbest indicated in Figs. 4 and 6, and the wires are inserted through theeye by means of a push rod 48 operating laterally in the bottom ofreceptacle 47 and s0 timed that upon the return movement of the partsheretofore described to the normal position, shown in Fig. 5, the pushrod 48 is actuated to forward a fastener 44 through the eye of thebutton, in general practice. It will thus be seen that in the practiceof the invention when the parts are in the normal position shown inFigs. 1 and 5, a button is in position to be fastened and a fastener hasbeen inserted through the eye of the button by the previous operation ofthe machine.

As best shown in- Figs. 10 and 11, the push rod 48 is secured by meansof a fastener 49 to a head 50 on a cylindrical slide 51 which operatesin a guideway 52 positioned at the side of the machine. A lever 53engages between projections 54 on the slide 51 and is actuate by aspring 55 normally to force the slide and push rod connected therewithinto its inner position, where said push rod will have entered throughan aperture 56 the bottom of the hopper or receptacle 47 and haveengaged with its end one of the fasteners and have forced said fastenerinto operative position through the eye of the button. As shown in Fig.4, the hopper 47 is V-shaped in cross section and has at the bottom aprojecting element 57, between the face of which and a wall of thehopper is a channel passageway 58 only with enough to permit a row offasteners 44 to pass downward, and the aperture 56 is in line with thebottom of said channel and in line with another aperture 59 leading intothe passageway 19 in the casing 15, so that when the fastener 44 ispushed through the last-named aperture it passes into channel 60 and 61in a bifurcated plunger member 62 and through the eye 63 of the button,where the same is held upon the top of an anvil bar 64 extended withinpassageway 19, as best shown in Fig. 7. The arm 53, which controls thepush pin 48, is pivoted at 65 to a stand connected with the frame and isintegral with another arm 66 having thereon a roller 67 adapted to beengaged by a cam bar 68 secured to and movable with a slide member 69which is rigidly connected with a plunger 70 which slides in a guidewayformed in the passageway 18 and 19 and in the plunger member 62. The cambar 68 is provided with a roller 71 which engages the side of the casing15. As will later appear, the cam bar is of such shape that itimmediately engages roller 67 and operates the same so as to withdrawthe pusher pin 48 from the bottom of the hopper channel 58 and holds itso withdrawn against the force of spring 55 until the end of themovements of the various instrumentalities for forming and securing thefastener upon the shoe and feeding forward and positioning the nextbutton to be fastened, the return of the pusher bar 48 under theinfluence of spring 55 operating to pass a new fastener wire through thebutton eye 63 and into position for the next operation.

As shown in Figs. 4 and 6, the cam bar 68 is connected with the head 69by means of a strap 72 which has a portion 73 extended through a slot 74in the wall 16 which is secured to said head and to the plunger 7 O, theportion 73 extending across the space 18 and through another slot 75 inwall 17, where it is connected with a rigid finger 76 adapted to engagea toe 77 fast on the shaft 28, by which said shaft and the buttonfeeding and holding members 27, 31, 40 are operated when the head 69 andparts connected therewith are forced downwardly. A roller 92 on a stud94 is so positioned that the bar 76 after passing the toe 77 engagesbetween said roller 92 and said toe, thereby firmly holding the partsduring the button-fastening action of the members. Head 69 carries a pin78, surrounding which is a spring 79 which is seated at its lower end ina socket 80 in the casing 15 and which operates to normally hold theslide head 69 and parts connected therewith in elevated position. A handlever 81, pivoted at 82 between the plate 16 and 17 and having thereon acam face 83 engaging the head 69, operates to force the same downwardwhen a fastening operation is undertaken, a shoulder 84 on said cam headbeing engageable with the angle 85 of the slide head 69 to hold theparts in normal position, as indicated in Fig. 5. The cross member 73,operating in slots 74 and 75, also effectivelv guides the slide head 69and the parts connected therewith in a vertical line as required.

Reference has been made to the plunger member 62, the plunger 70 and theanvil bar 64, which are the elements for forming the straight fastenerwire 44 into a staple 86, as shown in Fig. 8, and then fastening thesame, as indicated at 87 in Fig. 9. Having reference to Figs. 6, 7 and8. it will be apparent that the plunger rod 70 slides in a channel orway 88 formed in the front of the plunger 62, or between the bifurcatedportions thereof. On the side walls of this channel are a pair ofgrooves 89, which receive the ends of a pin 91 extending through thelower cleft portion 93 of the plunger 70. By this means the plunger 701s guided within the plunger 62 and has capacity for a certain amount ofdifferential movement relative thereto so that it may move thereinduring the downward movement for a required distance and on the returnmovement must cause the plunger 6:2 to move with the plunger 70 torestore the parts to initial position. The plunger 62 is caused to movewith the plunger 70 in the downward stroke for a certain distance bymeans of a catch 95 pivotally connected at 96 to the body of plunger 62and engageable in a notch 97 upon the back of plunger 70, as best shownin Fig. 5, the catch being pressed by means of a spring 98 so as toforce the catch against the back of plunger 70 and cause the same todrop into the notch 97 at the proper time. The catch has on each sidethereof a roller 198 which rollers engage cams 99 secured to the sidepieces 16 and 17 at each side of plunger 70 so that after the plunger 62has been caused to travel with plunger 70 the requisite distance to turnthe fastener blank 41 over the anvil bar 64 and form the staple 86 withthe side members thereof held in the grooves 89 and 90, as shown in Fig.8, and thereafter withdraws the anvil bar 64-, the plunger 62 be comesdisconnected from the plunger 70 which then travels independently sothat the curved ends 100 of members 93 engage the staple above the shoefabric 101 and form it upon anvil 102 in the fastener member 87, asshown in Fig. 9. In this operation it will be seen that the button eye63 passes between the members 93 and that the fastener is caused to turnin and grip the fabric 101 by engagement in sockets 103 formed in thetop of anvil 102. It is to be noted that the anvil 102 is removably andadjustably secured upon an extensionlOt of the base plate 21, as clearlyshown in Fig. 5. The removal of the anvil bar 64 is effected by downwardmovement of the plunger 62. As best shown in Fig. 3, the anvil bar 6tslides laterally in a guideway 105 formed in the casing 15. A pin 106connected with said anvil bar is surrounded by a spring 107 between theend of the guide channel 105 and the anvil bar 61 and normally operatesto hold the anvil bar in its projected and operative position. Rollers108 on the sides of anvil bar 64: are engaged by cam faces 109 on theplunger 62 immediately after said plunger has reached the positionindicated in Fig. 8, and continued movement of. the plunger to theposition shown in Fig. 9, through action of the cam faces 109. withdrawsthe anvil bar 64 from the path of plunger 70, which has. by this time,become disconnected from the plunger 62 and con tinues its movementacross the path vacated by the anvil bar 61 to effect the finalfastening action by engaging the formed staple 86 with the anvil 102.

The operation of my device has been fully given in connection with thedetailed description thereof. ()ne of the greatest advantages thereofconsists in its capacity to act upon wire blanks already formed and notcut from coils of wire during the operation of the machine. Theseblanks, as indi cated in Fig. 12, are specially formed so as to bepointed at the ends and oval or flattened at the centers. Or. ifdesired. the blanks may be flattened throughout their length. Blanks soformed make a much better fastener member than a member consisting ofround wire. The perforations made in the leather are cleaner. there isless liability to tear the leather: the fastener lies closer to thesurface of the leather. is less conspicuous and, holds the button betterthan is true of a fastener made of round wire. My machine is positive inits operation and cannot get out of order and requires no mechanicalknowledge on the part of the operator. The fastener blanks may befurnished in boxes, from which they can readily be poured in parallelrelation into the hopper or receptacle 47 and they will feed by gravitythrough the channel 55% to the delivery point at the bottom of saidchannel. In order to insure feed of the fasteners into the channel 58. Imay provide a plunger member 110 secured to member 7 2 and provided withcorrugated surfaces 111 which will be projected into the body offasteners at each movement of the machine and will tend to assistgravity in positioning the fastener blanks and causing them to keep thefeed channel 58 free.
